Specifically, the dripping member 36 and the heat exchanger 20 are both arranged in the accommodating space, the heat exchanger 20 is located below the dripping member 36, and there is a gap between the heat exchanger 20 and the dripping member 36. The water collecting member 22 is arranged in the accommodating space, and the water collecting member 22 includes a water collecting pipe body 221 and a guide portion 211b. It should be noted that the water collecting pipe body 221 is connected to the heat exchanger 20, and the water collecting pipe body 221 extends along the height direction DH of the gas-water separation device 1, and a water collecting hole 22a is opened at one end of the water collecting pipe body 221 toward the dripping member 36. The guide portion 211b is arranged between the dripping member 36 and the water collecting hole 22a to guide the droplets falling from the dripping member 36 to flow to the water collecting hole 22a.

[0063] According to the gas-water separation device 1 of this embodiment, it has both cooling and liquid collecting functions, and the dripping member 36 and the heat exchanger 20 are located in the same shell 10, which reduces the space occupied by the equipment and reduces the energy loss during operation.

[0064] Please continue reading Figures 1 to 3In this embodiment, the heat exchanger 20 is configured as a spiral plate heat exchanger. An installation space is provided at the radial center of the heat exchanger 20, and the water collecting tube body 221 is located in the installation space. Further, the heat exchanger 20 includes a first spiral plate 213 and a second spiral plate 214, and the first spiral plate 213 and the second spiral plate 214 are respectively wound around each other with the water collecting tube body 221 as an axis. The heat exchanger 20 also includes a top plate 211 and a bottom plate 212, and the top plate 211 and the bottom plate 212 are both connected to the inner wall of the shell 10, and the bottom plate 212 is located below the top plate 211. A heat exchange chamber 1a for accommodating the first spiral plate 213 and the second spiral plate 214 is formed between the bottom plate 212, the top plate 211 and the inner wall of the shell 10. The water collecting hole 22a penetrates the water collecting tube body 221 along the height direction DH of the gas-water separation device 1. The two ends of the water collecting tube body 221 extend to the top plate 211 and the bottom plate 212 respectively. Both the top plate 211 and the bottom plate 212 have a through hole 211a connected to the water collecting tube body 221. It should be noted that in order to facilitate the droplets at the dripping member 36 to fall and converge to the water collecting tube body 221, the upper surface of the top plate 211 can be provided with a recessed portion connected to the water collecting tube body 221, specifically, a recessed portion connected to the water collecting hole 22a, to form a guide portion 211b. After the droplets reach the top plate 211, they slide down and converge toward the water collecting hole 22a. Alternatively, the guide portion 211b can be constructed as a funnel-shaped opening upward or a slope-shaped inclined downward, and the guide portion 211b is connected to the water collecting hole 22a at the bottom end of the height direction DH of the gas-water separation device 1 to facilitate the droplets to converge to the water collecting tube body 221. In an embodiment not shown, the water collecting pipe body 221 may protrude upward from the top plate 211 or be located below the top plate 211 and communicate with and cooperate with the flow guiding portion 211 b.

[0065] In an embodiment not shown, the heat exchanger 20 may also be other existing types of heat exchangers.

[0066] See also Figure 2 and Figure 3Specifically, the water collecting member 22 also includes a first connection portion 222 and a second connection portion 223. The water collecting pipe body 221 extends along the height direction DH of the gas-water separation device 1 and is connected to the top plate 211 and the bottom plate 212. It can be understood that the water collecting hole 22a is located in the water collecting pipe body 221, and accordingly, the top plate 211 and the bottom plate 212 both have a through hole 211a adapted to the water collecting pipe body 221, so that the water collecting pipe body 221 is connected to the outside of the heat exchange chamber 1a along its own axial direction, so that the droplets dropped by the dripping member 36 can be discharged. Further, the first connection portion 222 extends along the axial direction of the water collecting pipe body 221 and is connected to the water collecting pipe body 221 along the radial direction of the water collecting pipe body 221. The second connection portion extends along the axial direction of the water collecting pipe body 221 and is connected to the water collecting pipe body 221 along the radial direction of the water collecting pipe body 221. It should be noted that, in order to facilitate the connection with the first spiral plate 213 and the second spiral plate 214, the second connecting portion 223 does not overlap with the first connecting portion 222. Figure 3 In the embodiment, the first connection portion 222 is connected to the first spiral plate 213 on the side away from the water collecting pipe body 221, and the second connection portion 223 is connected to the second spiral plate 214 on the side away from the water collecting pipe body 221. In an embodiment not shown, the first connection portion 222 can be connected to the second spiral plate 214, and correspondingly, the second connection portion 223 is connected to the first spiral plate 213. Further, an angle a is formed between the first connection portion 222 and the second connection portion 223, and the range of the angle a is: 90°≤a≤180°. Please continue to refer to Figure 3 In this embodiment, the radial line connecting the first connecting portion 222 and the second connecting portion 223 along the water collecting pipe body 221 passes through the center of the water collecting pipe body 221, that is, the angle a is 180°. In an embodiment not shown, the first connecting portion 222 and the second connecting portion 223 can be perpendicular (90°) or inclined (90° to 180°) to each other.

[0067] See also Figure 2 The first spiral plate 213 is connected to the water collecting member 22 and is wound around the height direction DH of the gas-water separation device 1. The second spiral plate 214 is connected to the water collecting member 22 and is wound around the height direction DH of the gas-water separation device 1. The first spiral plate 213 and the second spiral plate 214 are alternately arranged along the first direction D1, and the first direction D1 is perpendicular to the height direction DH of the gas-water separation device 1, so as to form the first flow channel 213a and the second flow channel 214a which are alternately arranged along the first direction D1 and are not connected to each other in the heat exchange chamber 1a.

[0068] See also Figure 1 and Figure 3The gas-water separation device 1 may further include a first inflow pipe 31, a first outflow pipe 32, a second inflow pipe 33, and a second outflow pipe 34. Specifically, the first inflow pipe 31 is connected to the first flow channel 213a and extends to the outside of the shell 10. For example, the first inflow pipe 31 is connected to the bottom plate 212. The first outflow pipe 32 is connected to the first flow channel 213a and extends to the outside of the shell 10. The first outflow pipe 32 is located above the first inflow pipe 31. The second inflow pipe 33 is connected to the second flow channel 214a and extends to the outside of the shell 10. The second outflow pipe 34 is connected to the second flow channel 214a. The second outflow pipe 34 is located above the second inflow pipe 33. The second outflow pipe 34 is located inside the shell 10 and protrudes upward from the top plate 211. Please refer to Figure 2 It should be noted that the unmarked holes on the top plate 211 are the connection holes with the second outflow pipe 34 , and correspondingly, the unmarked holes on the bottom plate 212 are the connection holes with the first inflow pipe.

[0069] See also Figure 1 and Figure 4 , the gas-water separation device 1 may further include a gas distributor 35. The gas distributor 35 is connected to the inner wall of the shell 10 and is located above the second outlet pipe 43. The gas distributor 35 and the second outlet pipe 34 are spaced apart in the height direction DH of the gas-water separation device 1. In order to allow the gas to better contact the dripping member 36 after reaching the gas distributor 35, the dripping member 36 is constructed to abut against the upper surface of the gas distributor 35; based on the actual use conditions, the dripping member 36 may also be constructed to be spaced apart from the upper surface of the gas distributor 35. It is easy to imagine that the gas-water separation device 1 needs to have a gas outlet and a liquid outlet, and the gas-water separation device 1 may further include a third outlet pipe 37 and a fourth outlet pipe 38. The third outlet pipe 37 is connected to the interior of the shell 10 and protrudes downward from the shell 10. The third outlet pipe 37 is located below the heat exchanger 20. For example, the third outlet pipe 37 is connected to the bottom of the shell 10. The fourth outflow pipe 38 is communicated with the interior of the housing 10 and protrudes upward from the housing 10 , and is located above the drip-catching member 36 . For example, the fourth outflow pipe 38 is connected to the top of the housing 10 .

[0070] In actual use, cooling water can be introduced through the first inflow pipe 31, and gas can be introduced through the second inflow pipe 33. The cooling water enters the first flow channel 213a, and the gas enters the second flow channel 214a, so that the gas and the cooling water can exchange heat in the heat exchanger 20. The cooling water after heat exchange is discharged from the first outflow pipe 32, and the gas after heat exchange is discharged through the second outflow pipe 34 and reaches the gas distributor 35. After that, the gas after heat exchange passes through the droplet catching member 36 evenly to catch the droplets, and finally is discharged from the fourth outflow pipe 38, realizing the gas-water separator process, and the captured droplets are collected at the water collecting member 22, and finally discharged from the third outflow pipe 37 through the water collecting pipe body 211.

[0071] According to the gas-water separation device 1 of the utility model, the functions of gas-water separation and cooling are integrated, so that the dripping member 36 and the heat exchanger 20 are located in the same shell 10, which reduces the space occupied by the equipment, and at the same time can speed up the efficiency of gas cooling and separation, reduce energy loss, and reduce production costs.
